Great site. I'm planning to add 4 white headlights and 2 amber tail lights to my son's Peg Perego tractor that he will be getting for Christmas. I plan to use the LEDs below. My plan is to wire them into the existing battery.

Am I missing anything? I plan to add in a switch and will use a terminal block to wire the four headlights up as well as the controller and two tail lights. Should the headlights be in series or parallel?

Don't forget to install a fuse for circuit protection. 5amp fuse would be more than enough. You can use one fuse on the power wire that feeds your terminal block. Wire the front circuit separate from rear since you only want the rear to strobe. The front lights that don't strobe should be wired in parallel. The rear lights you want to strobe will be wired to the controller outputs (left and right respectively).
